Dr. Juan Ramirez of Exponent will present two papers, co-authored with Dr. Russ Ogle, Mr. Andrew Carpenter, and Dr. Trey Morrison, at the 2008 Annual Meeting of the Venezuelan Society of Safety Professionals, October 29–31, 2008 in Caracas, Venezuela.
Dr. Ramirez will discuss the paper titled, “Common Causes and Corrections for Explosions and Fires in Improperly Inerted Vessels.” In this talk, causal factors and corrective actions surrounding improperly inerted vessel incidents are developed and compared based on several case studies of flash fires and explosions.
The second paper, "The Relationship Between Automation Complexity and Operator Error," discusses six case studies of explosions involving operator error in an automated process facility. For each case study, we consider the contribution of the existing engineering controls such as safety instrumented systems (SIS) or safety critical devices (SCD) and explore why they were insufficient to prevent, or mitigate, the severity of the explosion.
